Title: Device for storing and reproducing speech
Inventor: KOLEHMAINEN TIMO
IPC: H04M1/656
Filed: 1992-03-05
Abstract: A speech codec (2), a voice activity detector (4, 7) and a memory (3) can be used for storing speech without pause periods, and for reproducing the original speech with the required pauses. Speech is first converted with an Analog-to-Digital converter into digital form, and encoded with an encoding device into frames. Speech frames containing active speech are stored in the memory (3) until the voice activity detector (4, 7) detects a pause. A start mark bit pattern and information as to the duration of the pause are then stored in the memory. When reproducing the speech, speech frames are read in succession from the memory (3), and they are decoded and converted into analog form. Between the speech frames pauses are inserted, their positions and durations being read from the memory. The invention is particularly appropriate for use in a telephone answering device incorporated in a digital radio telephone. <IMAGE>

Title: An optical multiplexer
Inventor: SUTTON PHILIP
IPC: H04B10/11
Filed: 1992-07-10
Abstract: Light from a laser (10) is divided by a beam splitter (12) to provide signal (15) and reference (14) channels. The signal channel light is expanded (11) to illuminate an acousto-optic (AO) device (13). This leads to a spatial distribution of Doppler shifted frequencies. This spatial distribution then illuminates a spatial light modulator (SLM) (19) such that a number of parallel and discrete optical channels (112) emerge. In a local area network (LAN) the optical signal channels are coupled into a single mode optical fibre (22) and then heterodyned to the reference laser light from a further optical fibre (23) in an optical coupler (25). In a receiver the modulated light is detected (32) and the detected signal connected to the transducer of an AO device (35). The AO device (35) is illuminated by a receiver laser light (36) and the emerging modulated light is incident on a focal plane detector array (39) where each detector (310) then receives light corresponding to each of the transmitted channels (311). A secure free space communications system is possible by separate transmission of a delayed (43) unmodulated reference signal. The receiver is then arranged to include an identical delay (55) in the signal channels before coupling together the signal and reference channels (56) for modulating the AO cell (35). By this means the transmission delay lines (43) and the reference delay lines (55) must have delays which are equal within the coherence length of the source laser.

Title: Parallel processing apparatus
Inventor: HAMLIN DERRICK JOHN
IPC: G06F9/44
Filed: 1993-06-21
Abstract: A large number of processor cells (11), the majority of which are standard cells (12) and other special cells (13), are connected to a communication network (14) in the form of several binary trees. The cells (11) are connected at the leaf positions of the binary trees, and the nodes of the binary trees are formed by switching circuits that allow individual cells to control the formation of signal paths through the nodes. In operation, cells may be in a waiting state, a free state, a calling state, searching state, a communicating state, or an internal operation state. Cells (12) in the free state transmit a free signal into the network (14). Cells (12 or 13) in a searching state transmit a searching signal into the network (14) where, on meeting a free signal at a node, a route is formed from the searching state cell to a free state cell. A calling state cell (12) establishes, with a calling signal, a route through the network (14) to another cell identified by destination information in the calling signal. Cells (11) in the waiting state are waiting to be called by a cell (12) in the calling state. Expressions, in the form of lambda expressions, to be reduced to a final result are so distributed through groups of the cells (11) that only primitive operations and communication need be carried out by the cells (11).

Title: Fuel pressure control for high pressure direct fuel injection engines.
Inventor: MORIKAWA KOJI
IPC: F02M37/08
Filed: 1993-10-14
Abstract: The fuel pressure is kept high for a specified time or until the engine temperature goes down below a specified value after the engine has stopped in a hot condition, in order to prevent vapor lock in the fuel system. Also, a starter motor (59, Fig. 8) is prohibited from being switched on until the fuel pressure reaches a specified value in order to prevent a high pressure fuel pump 29 from being operated without lubrication. The valve 33 which is operated to provide a desired fuel pressure dependent on engine speed in the fuel injector supply line 31 is held closed to maintain the fuel pressure. The feed pump 25 is operated to build-up pressure before starter motor operation. The temperature at which the pressure is released may be dependent on the fuel volatility as measured by a sensor (66, Fig. 9). <IMAGE>

Title: Automatically closing water valve
Inventor: GOEHNER JOERG
IPC: F16K21/06
Filed: 1994-03-01
Abstract: An automatically closing, preferably by hydraulic motor, water valve (1), especially for manual opening, has a valve-closing member (10), which closes or releases a valve seat (12) and is preferably designed as a valve disc (10) having a stem (14). An auxiliary valve closure (16) carried by the stem (14) cooperates with a seat (13) on the member (10). Initial movement of the stem (14), from its position of full closure of the valve, lifts the closure (16) to relieve inlet pressure upstream of the member (10) and thus facilitates its opening on continued movement of the stem (14). The valve is arranged to close after a predetermined volume of flow and is particularly for use in watering plants. <IMAGE>
